Example how to upload a file to a BLOB storage container using SAS token authentication:

function UploadToBLOB ($file, $storage, $container, $sastoken) {
    $filename = (Get-Item $file).Name
    $uri = https://$($storage).blob.core.windows.net/$($container)/$($filename)$($sastoken)

    $headers = @{
        'x-ms-blob-type' = 'BlockBlob'
    }

    Invoke-RestMethod -Uri $uri -Method Put -Headers $headers -InFile $file
}

Postman

GET

Running GET with Postman for a given BLOB storage container using SAS token authentication:

Create a SAS token for the Azure storage account you want to use:

Use this SAS token in the postman GET request and postman will automatically show you the parameters of the SAS token:

https://{{accountName}}.blob.core.windows.net/{{containerName}}/{{fileName}}?sv=...

If you have a file available at {{containerName}}/{{fileName}} you should get a 200 response with the file content e.g.:

POST

Running POST with Postman for a given BLOB storage container using SAS token authentication:

The values I used:

I put some example log data in the body as raw input:

Running the POST command gives us the following result in Postman:

Viewing this file in Azure confirms the POST was successful. Here you can also see the optional header key x-ms-meta-metadatakey with value metadatavalue is set.

We can also view the file content and see it matches with what we added in the body of the POST command:
